Put baseon a flat surface and apply bead of approximately 3mm diameter on the 2 large panels, placing it about 3mm from the edge. Place back panel and press down to reduce joint thickness to 1-2mm. Apply beads of sealant to edge of small panel and corresponding large panel. Push edges of large and small panel together and hold in place.

Bottom line: A top choice for aquarium enthusiasts, offering durability, safety for aquatic life, and excellent sealing performance. Perfect for building or repairing tanks with confidence. Review: Excellent aquarium sealant - I recently bought a second hand aquarium which had seen better days, on investigation the sealant had pretty much failed all across the back on the bottom of the tank, although the sides were still solid , so I removed the base and stripped off all of the silicone and used the Everbuild Aqua mate silicone to re-attach the bottom glass and reseal all of the edges. It worked brilliantly. It was very easy to use, had a reasonable time (about 10 mins) before it started going too hard. I left the tank for 48hrs to fully dry and filled the tank. The seals are great even where I've gone over the original sealant. Considering I've never repaired an aquarium before I wouldn't have any reservations doing the same again in future. In my opinion 10 out of 10 ## Features - Aquamate Sealant - Size: 310ml - Brand: Everbuild ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0046QFTKU | | Best Sellers Rank | 9,126 in DIY & Tools ( See Top 100 in DIY & Tools ) 184 in Sealers | | Brand | Everbuild | | Brand Name | Everbuild | | Country Of Origin | United Kingdom | | Customer Reviews | 4.6 out of 5 stars 4,128 Reviews | | Global Trade Identification Number | 05029347120009 | | Included Components | CARTRIDGE & NOZZLE | | Item Form | Spray | | Item Type Name | pond sealant | | Item Weight | 172 g | | Item form | Spray | | Item weight | 172 g | | Liquid Volume | 295 Millilitres | | Liquid volume | 295 Millilitres | | Manufacturer | Sika Everbuild | | Manufacturer Contact Information | Sika Everbuild 41 Knowsthorpe Way, Leeds LS9 0SW | | Manufacturer Part Number | EVBAQUATR | | Model Number | AQUATR-EBD | | Pet Type | Fish | | Target Species | Fish | | UPC | 795186823900 | | Unit Count | 295.0 millilitre | | Unit count | 295.0 millilitre | ## Product Details - **Brand:** Everbuild - **Item form:** Spray - **Item weight:** 0.38 Pounds - **Liquid volume:** 295 Millilitres - **Manufacturer:** Sika Everbuild ## Images ![Everbuild Everflex Aqua Mate Aquarium Silicone Sealant – Fungicide-Free – Fast Curing – Clear – 295ml - Image 1](https://m.media-amazon.com/images/I/51DPxk7s20L.jpg) ![Everbuild Everflex Aqua Mate Aquarium Silicone Sealant – Fungicide-Free – Fast Curing – Clear – 295ml - Image 2](https://m.media-amazon.com/images/I/71byKxi0IbL.jpg) ![Everbuild Everflex Aqua Mate Aquarium Silicone Sealant – Fungicide-Free – Fast Curing – Clear – 295ml - Image 3](https://m.media-amazon.com/images/I/71cTAiT58vL.jpg) ![Everbuild Everflex Aqua Mate Aquarium Silicone Sealant – Fungicide-Free – Fast Curing – Clear – 295ml - Image 4](https://m.media-amazon.com/images/I/71u0bQtTBKL.jpg) ![Everbuild Everflex Aqua Mate Aquarium Silicone Sealant – Fungicide-Free – Fast Curing – Clear – 295ml - Image 5](https://m.media-amazon.com/images/I/71CP1FvG6nL.jpg) ## Questions & Answers **Q: it this just 100% silicone with no additives** A: The Everbuild AQUATR Aqua Mate sealant is a transparent high modulus acetic cure 100% silicone sealant and adhesive designed specifically for aquarium manufacture.

In my opinion 10 out of 10 ### ⭐⭐⭐⭐⭐ Works perfectly, powerful strong smell whilst curing *by R***S on 27 March 2023* My original fish tank had been dry for over 10 years, so before using it again I decided I should err on the side of caution and re-seal it. I choose this particular brand of sealant on the strength of other reviews. First time I've tried to reseal a tank, and I suppose I made a bit of a mess of it (the gap between the glass and the tape I put down was too much, and I cut too much off the end of the nozzle so I squirted out way more than needed. I was so worried about it drying too fast that I hurried the job so in the end it wasn't as smooth as it could have been... all of which are faults of the operator, not the sealant!). While curing it had a extremely powerful vinegar like smell, almost overpowering if I stuck my head inside the tank. I left it for 48 hours and then I tried filling the tank a bit at a time - all went well, no leaks nor did the tank collapse. (A reminder, I resealed the tank by cutting out the existing silicon inside the tank, but I did not dismantle the panes and glue them together again... I'm not that brave!). As it is the tank has been running for about 3 weeks so far without issue, so I'm happy enough with this Everbuild product and would be perfectly happy to use it again should I need to reseal any more tanks. Edit: 18May2024. Here I am revisiting this review after a year. The tank I sealed is still going strong with no leaks or related incidents since sealing back in March 2023. Edit: 24Jul2025. Tank retains its "no leaks" status for another year. ## Frequently Bought Together - Everbuild Everflex Aqua Mate Aquarium Silicone Sealant – Fungicide-Free – Fast Curing – Clear – 295ml, Trans - ProDec Extra Strong Caulking Gun - Unibond Sealant Finishing Tool, Effective Sealant Tool for a Smooth & Professional Finish, Sealant Smoother for All Sealants, Silicone Sealant Tool for Wall & Floor Applications --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/47965119-everbuild-everflex-aqua-mate-aquarium-silicone-sealant-fungicide-free-fast](https://www.desertcart.us/products/47965119-everbuild-everflex-aqua-mate-aquarium-silicone-sealant-fungicide-free-fast) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-11*
